seams-SEAT STRUCTURE.

To all. whom at may concern:

Be it known that 1, JAMES H. Coon, a citizen of the United States,residing at Detroit, in the county of Wayne, State of Michigan, haveinvented certain new and useful Improvements .in Spring-Seat Structures;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the figures of reference markedthereon, which form a part of this specification.

This invention relates to a spring seat or spring cushion construction,and consists inthe peculiar arrangement and association of partshereinafter fully set forth and pointed out particularly in the claims.

The object of the invention is to provide a structure wherein provisionis made for quickly and securely mounting the springs of an upholsteredseat or cushion so as to firmly retain them upon the supporting frame,and

wherein the arrangement is such as to enable the springs to be quicklymounted and readily removed, and at the same time produce a smooth andcompact structure.

The above object is attained by the arrangement illustrated in theaccompanying drawings, in which z Figure 1 is a plan view of a seat orcushion frame made in accordance with my invention.. Fig. 2 is atransverse section, as on line 2'2 of Fig. 1. Fig. 3 is a fragmentaryview in perspective of two of the'crossed straps of the frame. Fig. 4 isa fragmentaryview in plan, showing a modification of the structure.-Fig. 5 is a transverse section through one of the metal straps havingthe openings therethrough. Fig. 6 is a fragmentary view. in longitudinalsection through the other of the crossed straps, showing one of theloops adapted to enter and lie in the openings of the first mentionedstrap.

Referring to the characters of reference, 1 designates a rectangularframe formed pref erably of strong wire of suitable gage, across whichextend in one direction the metal straps 2 whose terminals are formedinto eyes 3 which embrace the wire 1 of the frame. Struck up from thebody portion of each of the straps 2 are a number of loops 4. Crossingthe straps 2 transversely are the metal straps 5 whose terminals areprovided with Specification of Letters Patent.

being provided with apertures, 7 regis j ter with and receive the loops4f'of the straps? 2, said loops passing through said apeltliiesk.

and extending above the; timeouts-snaps- 5. By thisarrangementthecrossed-straps of the fabric are securely united at their.

points of juncture and are firmlyheld against lateral displacement.Mounted-upon said stra s at the points where theycros's'atright ang esare the spiral springs-"8 which rest upon said crossed straps and areconfinedin place by means of the locking rods 9 which lie upon and crossthe lower coils 10 of said same time securely fastening the springs tosaid straps so as tomaintain them firmly in .a vertical position.

To prevent lateral displacement of the springs, there may be struck ufrom the cross straps 2 and 5, the lugs 11 W ch engage the lower coils1.0 of the springs, as shown, and prevent said springs shifting.

By the arrangement herein shown and dee scribed, a firm support. isprovided for the base of the spring which maintains it in a verticalposition, and at the same time provision is made for uniting the crossed:wmx. which support said spring by means of locking rod 9 which crossesthe lower coils of said springs and passes through the upwardlyprojecting loops of the straps 2. It will be observed that where the baror strand 9 is made continuous, asshown Figs. 1, 2, and 3, it serves asa truss to brace the straps 5 and add to the carrying strength thereof,en. abling the use of comparatively light material in said straps. Itwill further be observed that the frame formed of the rectangularmarginal strands 1 and the crossed. stra s 2 and 5 is comparativelysmooth upon the ottom side, thereby greatly facilitating the work ofupholstering.

In some instances it may be desirable toform the structure in narrowstraps or sections, as shown in Fig. 4, in which case the straps 5 willbe short, as shown in said Fig. 4 as well as the locking rods 9 whichwill correspend in length'to said short straps.

Having thus fully set forth my invention,

springs and pass through the loops 4 of the what I claim as new anddesire to secure'by Letters Patent is I 1. In a spring seat structure,the combination of the crossed metal straps, one of said straps having alocking member which passes through the other strap, a spring seated onsaid-straps at their point of crossing and a locking bar en aging thelower coil of said spring and saiddocking member.

V 2. n a spring seat structure, the combination of a plurality of metalstraps crossing at right an les, a number of said straps being providewith apertures and the remaining ortion of said straps being providedwith oops which pass through said apertures to tie the straps together,springs seated upon said straps at the juncture thereof, and a lockingbar passing over th'elower coils of said springs and through said loopsto tie the parts together.

3'. The combination in a spring seat structure, of the longitudinallyextending strap adapted to support a spring having a loop formedtherein, a transverse strap having an 26 aperture to receive said loop,a spring mounted upon said crossed straps, and a locking rod passingover the lower coil of said spring, and through said loop.

4. In a spring seat structure, the combination of the crossed straps,one of which is provided with an a erture and the otherv with a looppassing t rough said aperture, a coiled spring seated upon said crossedstraps, and means engaging in said loop and bearing upon the spring tolock said spring in position. a

5. In a spring seat structure, the combination of the crossed strapsforming a support for the spring, one strap having an aperturetherethrough, and the other having a projecting member which engages insaid aperture, means for looking the straps together and the springthereto,,-and means for preventing lateralmovement of the spring.

In testimony whereof, I sign this specification in the presence of twowitnesses. JAMES H. COOK.
